那表达式中El.eval("sequence('dgt','sequId')")；这种方式调用，都是new出来的对象吗？

如上，我们项目中只是用了NUTZ的表达式引擎部分，spring采用的是注解方式，大哥说的注册是哪块注册，可以提供示例代码吗？

对，通过js文件

{
	"EL":{
		"custom":[
			"org.nutz.el.opt.custom.Max",
			"org.nutz.el.opt.custom.Min",
			"org.nutz.el.opt.custom.Trim",
			"org.nutz.el.opt.custom.MakeUUID",
			"org.nutz.el.opt.custom.DoBase64",
			"org.nutz.el.opt.custom.DoURLEncoder",
			"org.nutz.el.opt.custom.TimeNow",
			"org.nutz.el.opt.custom.ByMake",
			"com.jettech.dgt.web.util.mathFuction.IN",
			"com.jettech.dgt.web.util.mathFuction.NOTIN",
		"com.jettech.dgt.web.util.mathFuction.EXCEL",
			"com.jettech.dgt.web.util.mathFuction.UNIONEXCEL",
			"com.jettech.dgt.web.util.mathFuction.SEQUENCE",
		]}
}

谢谢大哥，不知道为什么只能获取dao的bean,service获取不到，但基本上能解决问题了。
